Specification of Letters Patent.

Patented Dec. 4, 1908.

Application filed February 18, 1905. Rerial No. 246,270.

To aZZ whom it may concern.-

Be it known that I, STEPHEN O. Honou- TON, of Syracuse, in the county of Onondaga and State ofNew York, have invented a certain new and useful Telephone-Receiver, of which the following is a specification.

This invention relates to telephones, and is intended as an improvement u on the type of tele hone shown in Patent o. 759,280, grante to myself and F. M. Potter, Jr'., May 10, 1904, and has for its object to provide for the employment of a permanent magnet for the receiver of extraordinary dimensions, which is adapted to serve as a support for the other parts of the receiver. a

Figure 1 shows in side elevation, partially broken away, a telephone embodying my invention. Fig. 2 is a plan view and partial section of the receiver and its permanent magnet, which serves as a support for it, and the permanent or fixed sup ort for said permanent magnet, the dotted lines indicating the reverse position of the receiver and its supporting-arm. Fig. 3 is a transverse section of the receiver shown in 'Fig. 1, taken on the dotted lines A A. Figs. 4 and 5 are sectional views taken on the dotted lines B B and C C, Fig. 2; and Fig. 6 is a d etail showin in plan view the electromagnets supported by the arms of the permanent magnet.

1 represents what I herein term a permanent or fixed support for the transmitter and receiver, it bein herein shown as pivoted at 2 to a case 3, a though it may be fixed, if desired. This support is made as a shell or 7 case of any suitable size, shape, and construction.

4 is the transmitter, which is preferably mounted on the support 1.

V The receiver has a air of electromagnets 5 (see Fig. 3) contained within its case, which are located back of the usual diaphragm, and

- the cores of said magnets are extended rearward into engagement with the rear wall of the case, being thereby supported. The

permanent ma et 7 for the receiver is herein shown as of t e' horseshoe t e, comprising T e extremities of the arms of said permanent magnet extend through a hole in the side .of the receivercase and arebiturcated to embrace the cores of-the electromagnets, and said cores are pivto the extremities of said otally connecte Harms by a suitable pin or pins. 20 or otherapparatus without departing from the spirit x 2, In'a telephone,

wise. The receiver is thus pivotallyconnect- '5 5 ed to the extremities of the arms of the permanent magnet and is free to rock thereon.

The arms of the ermanent magnet are bent, as at 8, near the heel, and the heel is circularly formed to embrace the circumfer- 6o entially-grooved head of a stud 9, the shank of which projects into the support 1 and is pivoted at 10 to said support and-is held in a predetermined position y a suitable spring 11, which bears upon or against its inner end.

The permanent magnet for the receiver thus serves as a supporting-arm for the receiver and is bent for the purpose of holding the receiver in a certain osition with res ect to 1 the transmitter, an its circularlyormed 7o heel frictionally embraces the stud 9, so that it may be turned on said stud to occupy a osition at either side of the transmitter and to remain in whatever position it may be set.

The conductors leading to the receiver (not 7 5 herein shown) pass between the arms of the permanent magnet 7 to an opening 12 in the head of the stud 9 and through openin s 13' (see dotted lines, Figs. 2 and 5) in the shank thereof and are connected to any suitable switch (not shown) adapted to be actuated by the rocking movement of the stud 9 on its pivot 10 to connect the receiver with the talking-circuit.

By utilizing the permanent ma net of. the receiver as a supportin -arm for t e receiver it may be made of extraordinarydimensions and the efficiency of the receiver increased.

It 'will be understood. that in lieu of the described means for rotatably connecting the 0 permanent magnet to its support any other suitable means may be substituted therefor, and, furthermore, more or less changes may be made in the other component parts of the and scope of my invention.

Having thus described my invention, what I claim as new, and desire to secure by Let ters Patent,*is v 1. In a telephone, the combination with a fixed support, of a permanent magnet of the horseshoe type for the receiver, the heel of which embraces said support and a receiver connected to the extremities of .the arms of said magnet, substantially as described. 1 1o 5 the combination with a fixed support, of a permanent magnetof the horseshoe type .for the receiver, the heei oi I scribed.

which embraces said support, and a receiver pivotally connected to the extremities of the arms of said magnet, substantially as de-- scribed.

3. In a telephone, the combination of a fixed support, a permanent magnet for the receiver, connected to said support, areceiver-diaphragrn, and electromagnets ioc'ated back of the receiver-diaphragm, the cores of which are pivotally connected to said permanent magnet, substantially as de- 4 In a telephone, the combination of a fixed support, a permanent magnet of the horseshoe type for-the receiver, connected to said support, a receiver-die hragm, a pair of electromagnets' located has of the receiverdiaphragm, the cores of whi'ch are pivotally connected to the extremities ofthe arms of said magnet, substantially as described.

5. In a telephone, the combination of a fixed support, a" transmitter attached to it, a 1 stud on said support near the transmitter, a permanent magnet of the'horseshoe type for the receiver, the heel of Which irictionally embraces said stud, whereby said magnet may be turned'to occupy a position alt-either side of the transmitter, and a receiver at'-- tached to the extremity of said magnet, sub stantially as described.

' senses fixed support, a transmitter attached to it, a

stud on said support, a permanent ma net of the horseshoe type for the receiver, the eel of the horseshoe type for the receiver, the heel of which embraces said stud, and a receiver connected to the extremities of the arms of said magnet, substantially as described.
